n1'0 of a dump truck having ak rotatable membery fitted into an open space between the boty tomA andthe rear endr ofy the body ofithek truck, the rotatable member being provided with spirally arranged lribs or raised por- A tions which willl evenly and progressively distribute the materials carried Vby thebody of the truck over thevroa'dbed. Y f

A further object of the invention is the provision of a cylindrical member provided "2c with spirally arrangedribs and'spacesfbe tween said ribs for progessively and positively forcing materials from the truck kbody outwardly from the rear end for distributing materials evenly overv the roadbed and at 325 @thickness which may -be ydetermined at will,

the materials being delivered at an angle across the longitudinal axis of the road-way.`

This invention will be best understood from a consideration ofl the following detailed der'-30 scription, in view'of the accompanying draw.-

ings forming a` part of the specification;

neverthelessit is to be 'understood that the invention: is not conned to the disclosure, be"- ing susceptible of such changes and modi'ca- ""35 tionswhich shall define-no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings A.

Figure'l is a side view in 4elevation of a '-40 dump truck constructed in accordancev with the principlesv of my invention, Figure 2 is a fragmentary vertical section takenv along the 'line 2 2 o f Figure 5,

Figure 3 is a vertical sectionl taken along .45 .the line 3--3 of Figure 1, f

'15.0 ings,'10 generally designates a truck body which is driven by a power plant (not shown) but which is normallyy located beneath the hood 1'1 of the truck. The-shaft l2 extends from the power plant and is driven thereby. The usual transmission 13 is located between the shaft 12 and the vehicle driving shaft 14.

A truck body is mounted upon the truck 10'and is pivotally mounted on a shaft 21 carried by bearings 22 and' 23 secured at 24 to the side walls 25 of the dump body. Standards 26 and 27, respectively, support the bearings 22 'and 23 and are secured to a U-beam 28 secured to the chassis or truck 10. A tailgate or closure 29 for the rear end of the dump body 20 is located'at an angle to the vertical so that the vlower end of the'gate which is adjacent spirals 31 formed onk the shaft 21 will be located inwardly of the rear end of the body.

It will be noted 'that that portion of the shaft 21 which contains the spirally arranged ribs or projections 31 is disposed in the space at the rear of the dump body 20 which is defined' by the lower end 33 of the tailgate 29 anda floor 34 of the dump body. The floor where the shaft extends across the dump body is cut out along the curve which conforms to the curvature of the spirally arranged member 31 and said member is located'within the cutout portion 35 in order to normally maintain the dump body closed at this point. The spirals 31 are' so spaced as to provide grooves 36 through which the `materials carried 'in the dump body 20 are forced during the rotation of the shaft 21.

' 'A gear 40vis'mounted in a casing 4l at one end of the sha-ft 21 and is secured to said shaft and driven by a gear 42 secured to a shaft 43. This shaft extends longitudinally ofthe dump body and has one end projecting into a housing 45 and a gear 46 is secured to the end of the shaft 4 3 and is located within the1housin'g 45. A gear 47 is secured to a shaft 48 and is also located within the hous- ',ing45 and meshes with the gear 46.

A speed-transmission 50 is connected vbef tween the shaft 48 and a shaft 51 which extends into a kclutch housing 52. This transmission is controlled by a link 53 and alever 54 located adjacent the drivers seat 55 so that l i lever be readily l y sion mechanism V 5 0.
